Cardbocchi can't shake the feeling he's being watched. One day, on his way home, he feels like he's being followed, so he runs...straight into a group of delinquents! Meanwhile, Haruo is looking for new choir members. Again.
Awful singers with a ton of enthusiasm 
are the absolute worst to deal with.
المغنّون السيّئون بالكثير من الحماس
هم أسوأ من قد أتعامل معهم
Am schlimmsten sind Leute,
die motiviert, aber unfähig sind.
Los cantantes malos
con entusiasmo son los peores.
Los malos cantantes
con mucho entusiasmo son los peores.
C’est chiant d’avoir un mec motivé
qui chante aussi mal !
Non c'è cosa più seccante
di uno scarso con tanto entusiasmo.
Nada pior do que um
incompetente motivado!
Таких любителей попеть 
от души очень сложно учить.
